| description | A novel wide-band optical frequency shift technology by using a compact single-frequency Brillouin fiber laser (BFL) configured with high-doped Er<sup>3+</sup> fiber and high nonlinear fiber (HNLF) is proposed and investigated experimentally. By adjusting variable optical attenuator (VOA) to eliminate the free-running oscillation in the fiber ring cavity, a stable single-frequency BFL will be considered as local oscillator (LO) for coherent detection in Brillouin optical time domain reflectometry (BOTDR) sensing system. The BFL operates at 1549.06 nm red-shifted 0.084 nm (about 10.5 GHz) from the pump seed laser. The laser signal-to-noise ratio (SNR) is larger than 50 dB and the laser linewidth is about 3.1 kHz. Applying the BFL to the BOTDR system, the measured results show that the beat frequency between the spontaneous Brillouin scattering (SBS) and the LO is about 420 MHz and the frequency fluctuation is less than ± 2 MHz for 20-km sensing fiber. |
